This invention relates to kan appliance for picking cotton and the like and the. principal object thereof is to provide a suction noz-v zle that can be directedtoward the ripecotf ton or ripe unopened bolls with means connected with the nozzle for catching the product and drawing it into the nozzle so that suction will carry it on to a receiver. To that end I provide a nozzle having a suction operated turbine arranged adj acentits inlet end with means connected to the turbine for actuating a pair of rollers connected to a fixed and movable jaw on the nozzles that are driven to catch the cotton and draw it into the nozzle as stated.

Features of invention are shown in the construction, combination and' arrangement of parts whereby a nozzle is provided that is especially adapted to pick cotton that tena- Vciouslyclings to the cotton bolls or to gather o'cotton that ordinary suction will not dislodge rom the bolls and also to pick'and crush the ripe unopened cotton bolls.
